OMP Hobby BIGHORN 49

OMP Hobby 49” Bighorn is a sport RC model airplane built in the traditional way: balsa and film cover.

The airplane features light yet strong structure, and abundant power, making the airplane easy to fly and
capable of a lot of advanced aerobatics, such as hover. The big wheels provide enough clearance for easy
takeoff and landing on grass field. Flaps (if equipped) of the airplane makes it ideal for short field takeoff
and landing, and air brake in crow configuration.

The optional 49” Bighorn receiver ready version is an almost completed finished kit in factory. Motor, ESC,

servos, Ailerons, flaps, elevator, are all installed. Landing gear is preassembled. Propeller is included in the
kit. It takes no more than an hour to put the kit together and ready for the sky.
